ect a position which is not in the immediate vicinity of cables carrying very high currents.
These cables generate relatively powerful electro-magnetic fields, which could have an
adverse effect on the gyro. Precisely the same applies to ignition cables if your model is
powered by a large-capacity petrol engine.
If you wish to use the RO-WING 300 in conjunction with a radio control system operating in
PCM mode, please note the following point: input Rx1 must be connected to a receiver out-
put with a lower channel number than Rx2. The gyro's processor can only process the sig-
nals for the two aileron channels if there is a distinct interval between them, i.e. they must
not arrive simultaneously. With a PPM system the individual channels are sent in sequen-
ce, and the interval between signals is long enough to eliminate any problems which might
arise. With robbe/Futaba PCM systems you will be using channel 1 with channel 5, 6 or 7
for the two ailerons, and in this case you will also encounter no problems at all. Please
check that the PCM process used by your RC system satisfies these conditions.
If the gyro comes loose in its mountings, the model is virtually bound to crash, and for this
reason the gyro must be installed carefully. It is possible to vary the rate of gyro suppressi-
on when you operate the aileron control by assigning a mixer between the aileron and
"AUX" channels.
The linkage to the control surfaces must be as direct (slop-free) and free-moving as possi-
ble, as this improves overall precision and reduces current drain. If you are using the gyro
in a small or high-speed model (turbine models), it is important to set the gyro gain to a very
low level, otherwise the ailerons may oscillate and overload the airframe.
